GAS Tonen.

Application led January This invention relates to a torch used for melting purposes and the like, the general object of the invention being to provide a torch which will use gas as fuel and which is so formed as to produce a flame of intense heat with the minimum amount of fuel.

Another object of the invention is to so form the parts that the device can be manufactured to sell at low cost, will be simple in' 'operation and can be easily handled in all situations where a supply of gas can be secured. x

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying f drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the device.

Figure 2 is a perspective view showing how the device can be handled.

Figure 3 is an enlarged sectional ldetail view through the nozzle parts.

Figure 4 is a section on line 4--4 of Figure 3.

In these views, 1 indicates a pipe which forms the handle of the device and which has a cock 2 at its rear end to which the supply pipe 3 is connected, this pipe 3 being adapted to be connected to a gas supply. An elbow 4 is secured to the other end of the pipe 1 and a tip 5 is threaded in said elbow. The bore 6 of said tip is very small and said tip is provided with enlarged threaded parts 7 and 8 which are spacedapart to form an annular recess 9. The enlargement 8 is provided with a number of longitudinally eX- tending notches 10 which extend into the bottom wall of the recess 9, these notches forming air passages. A cup-shaped member 11 has a threaded hole in its bottom which engages the threaded part 7 and a nozzle 12 is threaded on the enlargement 8, the base of the nozzle being surrounded by and spaced from the outer end of the cup- .shaped member so that air can pass between the two members into the cup-shaped member and this air will then pass through the 14, 1925. *serialy No. 2,362.

the tip and thus produce an inflammablemiXture which will burn at the end of the nozzle. The nozzle is made with a Venturi passage 12. This arrangement of parts will produce a flame of intense heat whichwill melt copper and other substances very quickly and with the minimum amount of gas. A clip 13 is fastenedy to the pipe 1 to form a support for the device when the same is not in use, this support holding the nozzle in an upright position, as shown in Figure 1.

This device can be manufactured to sell at lowcost and it can be attached to a gas supply of a dwelling or other building. It is very light so that it can be easily handled and by attaching a long flexible tube to the torch it can be carried about without difficulty. f

The device is especially useful in soldering the iridium on gold pen pointsthough it will of course .be understood that it can be used for other purposes. s

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

Vle desire it to be understood that we may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with- -in the scope of the appended claim.

l/Vhat we claim is A device of the class described including a pipe forming a handle and an elbow connected with one end of the pipe,V a tip threaded into the outer end of the elbow, said tip being formed with enlarged threaded parts spaced to provide an annular recess, said tip having one of its enlarged threaded parts formed with longitudinal extendingr notches, which extend into the bottom wall of the annular recess to provide air-passages, a cup shaped member threaded on to one ofthe enlarge-d portions adjacent V HARRY E.
